Which Gives Better Light For Growing Plants In A Greenhouse Fluorescent Or LED

It can be confusing to know, which gives better light for growing plants in a greenhouse fluorescent or led because they both have advantages and disadvantages. The best organic light depends on your specific circumstances, but most greenhouse gardeners choose LED lights because of the spectrum of light they offer. So why does choosing the best light matter in a greenhouse?

Growing lights and the proper use will help the greenhouse mimic the necessary conditions for the growth and development of your plants. But because there are different types available, gardeners can get confused not just with the color, but also with the specific light. Below are the differences between fluorescent and LED so that you can find the greenhouse’s ideal growing light.

Battle of Growing Lights: Which Gives Better Light For Growing Plants In A Greenhouse Fluorescent Or LED?


What are LED grow lights?

LED grow lights, or light-emitting diodes, are gaining popularity for greenhouses because they have specific light spectrums. This makes it easier to select a LED to grow light that will meet your plant’s needs, and typically, they are in blue and red or as a full spectrum. Besides, some LED grow lights allow adjustment of wavelengths, so you can control them as your plants grow. 

Like a natural LED light, the most significant advantages of LED grow lights are that they are durable and energy-efficient. To make them even more reliable, some models have cooling systems as well. However, they are at a higher price point compared to other grow lights.


What are fluorescent grow lights?

Compared to LED grow lights, the phosphor powder’s chemical composition will dictate the color of fluorescent grow light. While you don’t have control over the wavelengths, farmers commonly use fluorescent grow lights for seedlings. Additionally, their lower costs make them a more economical choice for a small-scale greenhouse. 

Their durability and limitation on wavelengths make fluorescent grow lights second to LED lights as a greenhouse choice. But if you want to start vegetables indoors or if your plants have medium or low lighting requirements, fluorescent lights would be enough. A quick tip for a brighter grow light is to choose a narrower bulb. 


Which grow light is sufficient for the greenhouse?

LED grow lights give better light compared to fluorescent lights because of their light spectrums, and some allow adjustment of wavelengths for specific growth stages of plants. However, the term better light is also applicable for fluorescent grow lights because they’re easy and reliable for sowing seeds. The University of Maryland Extension mentioned that there are many fluorescent lights that you can choose from to grow healthy transplants. 

The College of Agriculture & Natural Resources discovered fruiting in tomato plants within five weeks using T-5 fluorescent lights. Therefore, choosing between these two types of growing lights will depend on your specific needs and conditions. Trial and error may also help you identify which will work best for your greenhouse. 


Which grow light is more energy-efficient?

As mentioned previously, LED growing lights are more energy-efficient, but both lights vary in their efficiency depending on types. For example, cool white LED growing lights and straight-tube fluorescent organic lights are similarly efficient for both models. Remember that you must consider how much energy the bulb will use for the light it produces. 

However, what makes LED growing lights the winner in this factor is that the fluorescent bulbs require replacement as quickly as annually. The quality will decline when you notice darkening on the ends of the tube. In turn, this will also affect the bulb’s efficacy. 


Which grow light has better color?

To say that a growing light produces a better color, one must identify what your plants need. Both LED and fluorescent grow lights offer warm and cold colors but remember that plants need them both. Therefore, you must choose a full-spectrum fluorescent or LED light for your greenhouse and adjust accordingly.

There are also specialty LED grow lights that will give you the proper balance. These lights have warm and cold diodes in a single bulb, which is more convenient than a fluorescent fixture with two bulbs. Some LED grow lights also allow adjustments so you won’t need to buy other types as your plants grow. 


Which grow light is more cost-effective?

If you’re using a small-scale greenhouse, you can save in costs with fluorescent grow lights. However, cost-effectiveness is also applicable to LED grow lights. They may have a higher purchasing point, but they don’t need replacement often.

In the long run, you’ll have minimal expenses with LED grow lights. If you want to use a full-spectrum or T-5 fluorescent grow light, they will also cost higher anyway. Therefore, it would be more economical to choose LED, but small-scale gardeners can use fluorescent lights. 



LED grow lights are the answer to, “which gives better light for growing plants in a greenhouse fluorescent or LED?” They offer specific light spectrums and adjustable wavelengths to match your plants’ needs. However, small-scale gardeners may also benefit from cheaper fluorescent. 

Additionally, fluorescent lights that are full-spectrum or T-5 are especially helpful for starting crops indoors.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
